INHALATION |
|
| |
Acute exposure: |
|
| |
|
·
When heated: Inhalation of
fumes can cause fume fever. |
|
| |
Symptoms: |
|
| |
|
· Sweating,
shivering, headache, fever, chills, thirst, muscle aches, nausea, vomiting,
weakness and tiredness.
· The
symptoms occur 4 to 12 hours after exposure and usually last up to 24 hours.
|
| |
SKIN CONTACT |
|
| |
|
· No irritation
of skin for short exposure. |
|
| |
Chronic exposure: |
|
| |
|
· In cases of
poor personal hygiene, occupational dermatitis (oxide pox) can occur where zinc
oxide dust
combines
with debris and bacteria to block sweat glands on the skin.
|
| |
EYE CONTACT |
|
| |
Acute exposure: |
|
| |
|
· May cause
redness and irritation. |
|
| |
Chronic exposure: |
|
| |
|
· Repetitive of
prolonged exposure to zinc oxide fumes may cause conjunctivitis. |
| |
INGESTION |
|
| |
Acute exposure: |
|
| |
|
·The toxic dose
is 2 grams/kilogram and over. At the extreme, zinc oxide can cause
gastro-enteritis. |
| |
Chronic exposure: |
|
| |
|
·Permeates the
placenta and excreted through maternal milk. |
